Looking for a hard tonneau cover for your 2024-2026 Toyota Tacoma with a 5' bed? The BAKFlip MX4 (Gen 3) Hard Folding Tonneau Cover, part number 448446, is cut for that application. The hard panels protect your cargo from weather and prying eyes, and the folding design opens the bed in one move.
The BAKFlip MX4 is BAK's step-up folding cover. This Gen 3 version adds stronger panels, a tighter seal and a re-engineered auto-latch.
Tacoma owners tend to load the bed with camping, biking and trail gear, and a lockable cover keeps it secure at the trailhead and dry on the road.
Open the bed, keep the cover. Drop the tailgate, release the rear latch, and fold the cover up against the cab for 100% bed access, even for large cargo. Re-engineered prop rod clips hold it open, premium rubber bumpers protect the cab and the cover, and the third brake light stays visible in every position.
A low, tidy profile. Textured matte black on every component and a flush fit with the rails make the cover look like it belongs on the truck.
Gen 3 strength. The top panels are multi-layer aluminum over a high-density polymer core and are 22% stronger than the original MX4, while precision-engineered aluminum side rails and frame keep the cover rigid. It is rated for 400 lb of evenly distributed weight.
More for rain and road spray to get past. Updated EPDM perimeter seals, tight-fit clamps, a longer dual-action tailgate seal on most applications and an integrated drainage system all work to keep the bed dry.
It locks itself. Close the cover and the latch engages. Gen 3 uses redesigned latching panels and lock hardware that BAK built to resist forced entry better than the Gen 2 design.
Before you order: It requires the Toyota Deck Rail System. Also match the bed length shown in the fitment line above.
Assembled in the USA and covered by a five-year limited warranty, the BAK 448446 is the Gen 3 upgrade for owners who want a stronger, tighter-sealing folding cover. Order it from Track Ready Products and check the bed length above.
The Gen 3 click-in mounting makes this a one-person job, typically 30 minutes or less, with no cutting, trimming or drilling on most trucks. Clamps and hardware are included.
Start with a clean set of rails. Position the cover, tighten the clamps evenly, and run it through a full open and close cycle to check that it moves freely and latches.
Recheck the clamps after about a week, wash with mild automotive soap and water, and clear off snow and ice before opening. Keep the cover secured at all points whenever you drive.
